The Princess of Wales returned "buzzing" from her trip to Italy promoting the early years development of children and has become a "pro" on the subject, her husband says.
Prince William discussed Kate's first official foreign tour in more than three years during an appearance on Heart radio's breakfast show.
He said his wife is "edging herself back" into doing more overseas visits following her successful cancer treatment but cautioned royal trips take their toll, so they have to "make sure she's okay and rested".
